Hey guys I just got a new flatbed trailor. 20 footer with 2 7000 lb axles. I am having trouble with the trailor making a bad vibration in my truck. I am thinking it must be the wheels out off balance or something. My steering wheel shakes terrible with the trailor on. Theres no way I can use the trailor this way. I am taking it back to the dealer to get it figured out. A new trailor shouldnt act this way. Any thoughts on this guys. Any help wopuld be appreciated.
